Sol. The correct answer is the option ”d”. Ripples are the instant effect of wind on water and they die down as quickly as they form, as the surface tension of the water dampens their efforts. Waves always travel in the same direction as the wind is blowing: if the wind changes th...
A. To harden water. B. To lower the surface tension of water. C. To increase the viscosity of water. D. To make water cloudy. 相关知识点: 试题来源: 解析 B。中文解析:表面活性剂在洗涤剂中的主要作用是降低水的表面张力,使水更容易扩散并渗透到污垢和污渍中,从而起到清洁的作用。A 选项是使...
1 What is surface tension?1.1 Surface tension and its definitionSurface tension is one of the most fundamental properties of liquid and solid phases.Surface tension governs a diversity of natural or technological effects, including floa-ting of a steel needle, capillary rise, walking of water strid...
Surface tension is like a “skin” of water. The “skin” is there because water molecules(分子) are drawn to each other. One example on Earth is that some bugs can “walk on water". Most of the time, gravity is too strong and it breaks the “skin”. But with zero gravity in ...

molecular adsorption at the gas-liquid interface was introduced and the rate of adsorption was determined from measurements of the dynamic surface tension. T... D Beneventi,B Carre,A Gandini - 《Colloids & Surfaces A Physicochemical & Engineering Aspects》 被引量: 113发表: 2001年 Water Uptake ...
When the surface tension is lowered, it is easier for liquids to mix with other materials.Detergents, for example, lower the surface tension of water, which allows water to penetrate the fibers of clothing and rinse away dirt. Watch spiders walk on water and observe the effects of surface te...
